The Importance of Timing in the Olympics

Marksmanship in the Olympics often comes down to a shooter's ability to predict this lock time. A human holding a firearm, when you pull the trigger to every action, there's an equal and opposite reaction. The fact that you're moving a physical hammer into a firing pan means that the gun itself has to move in response to that. It might deform at a different rate than the opposite cartridge. Depending on the day it was formed, depending on the alloy of brass. How much air there was in the mixture in the pour. The stoichiometry. On the day that it was made, all that stuff matters. All these different things.
